I created an account with Avalara and activated the module in X-Cart 4.6.5. When I tried to get a tax calculation in the cart, nothing showed up. The log showed this error:

RequiredError: CustomerCode is required.

I poked around in this file:

modules/AvaTax/func.php

Each transaction submitted to Avalara must have a unique Customer Code attached to it. The default programming for the routine uses X-Cart's Customer ID, which does not exist for unregistered customers.

So I modified the code to use the customer's email address instead.

In function func_avatax_get_taxes, I added the line with 'email':

'id' => 1,
'email' => 1,
));

In function func_avatax_get_taxes_internal I changed this line:

$request->setCustomerCode(!empty($customerInfo['id']) ? $customerInfo['id'] : '');

to this:

$request->setCustomerCode(!empty($customerInfo['email']) ? $customerInfo['email'] : '');

It's working for me, but do your own testing!
